that's interesting, but I am using dsfml by jebbs( not derelict 
), and I checked the code, it appears that the most of the class 
allocates resource and then freeing it in Destructor i.e

class RenderWindow {
     private sfRenderWindow* _window;
     public {
          this() {
             _window = sfRenderWindow_create(/*parameters*/);
          }
          //couple of other functions
          ~this() {
              sfRenderWindow_destroy( window );
          }
     }
}
//not a very accurate representation, but should get the message 
pretty clear

which I am very concerned about leaking resources, the tutorial 
did just not use scoped!, instead it directly use new, but what 
about leaking resources ?
